REV COUNTER INSTRUMENT
Fault finding - Role of components
–Rev counter: engine speed signal. The engine speed signal is sent to the rev counter by the injection computer on
the multiplex network.
–Electronic stability program (ESP) indicator light:
The ESP indicator light comes from the ABS and is sent by the multiplex network.
The ESP indicator light is an amber coloured light.
The indicator light is tested for 3 seconds by the rev counter when the + after ignition feed is switched on (only if the
ESP function is present on the vehicle and programmed on the Renault production line or in After-Sales).
This indicator light will only be activated if the configuration LC002 ELECTRONIC STABILITY CONTROL (ESP) is
WITH.
The electronic stability program indicator light gives information about the following statuses of the ESP system:
–Lighting function - dimmer lighting:
The rev counter lights up in accordance with the illumination of the lights and the instrument panel.
The dimmer lighting function is controlled by the instrument panel using the control located under the steering wheel.
The request is sent to the rev counter by the multiplex network. The rev counter varies the light intensity in
accordance with the signal received.ESP system statusRev counter Instrument panel

REV COUNTER INSTRUMENT
Fault finding - Function
System outline
The system is composed solely of an offset rev counter on the instrument panel facing the driver, which incorporates
its own computer.
The function of the “rev counter” system' is:
●To display the "engine speed" signal image in rpm sent by the injection computer on the multiplex
network.
●To identify the traction control system warnings on equipped vehicles.
Depending on the configuration, when the lights are switched on, the rev counter backlighting may vary depending
on the instrument panel backlighting dimmer request, the light signal is sent on the multiplex network by the
instrument panel.
